A town in Normandy, France recently announced a 0.6-mile stretch of road covered in solar panels that’s safe to drive on.

Ultimately, it’s possible this technology could make its way to the states.

Despite efforts made by some, the wind energy revolution continues. Costs are dropping, billions are being invested, and companies around the world are working hard to make wind turbines safer, more effective, and cheaper.
